FOR CARBONATING DISPENSING LIQUIDS Edward Jacobs, New'York, N. Y. Application March 11, 1932, Serial 'No. 598,256

' '1 Claims. (01. 225-18) My invention relates to receptacles for carbonating and dispensing" liquids, 'andparticularly to receptacles of convenient size for home use,

that is, receptacles capable of being transported F for personal use or used in homes, camps, and while traveling as contrasted with apparatus used commercially in stores and bottling plants for carbonating liquids. r

One of the principal.objects of my invention is to provide a carbonating receptacle and a capsule for use in connection therewith, the receptacle being provided with .a chamber into which the capsule can be inserted after the receptacle has been filled with liquid and closed, the construction andarrangement being such that there can be nocontact between the liquidand the surface ofthe capsule so that the liquid will not be contaminated by germs ordirt which may have been deposited on the exterior of the capsule when it wasbeing manufactured, packed, or otherwise handled. A I

It is also an object of the invention to provide a specially constructed capsule especially 'designed .to receive solid carbon dioxide of a predetermined quantity whereby the charging of the capsule is greatlyfacilitated and made possible by a new, easy, and cheap method as compared with the usual methods of charging capsules with liquid carbon dioxide. Under my invention carbon dioxide can be 'readilyplaced in the capsule in solid form and the parts of the capsule then united and tightlysealed to prevent escapement of the carbon dioxide when it liquefies or gasifies.

, This object is 'accomplishedby providing a cap-' 5 rule composed of twopieces, one being relatively long and having a wide mouth so that the carbon dioxide can be readily inserted through the wide open mouth; after which the other part, which is relatively short and of cup-like forma- 1 4 ti'on is united to the first part by clamping togather flanges at -the relatively wide open mouth of the first part asherei'nafter described in detail,

In providing the above construction of the capsuie, I- also provide a radial flange around the of the'capsule located and adapt- 8 b t 'iwith the capsule receiving chamber of the receptacle to facilitate removal or th capsule from-the chamber after'it has used to carbonate the liquid. 1

Another object of'the invention is to provide'in connection-with the capsule chamber and rejceptacle elficient means-for piercing the capsule and directing gas, therefrom into the receptacle 5 m admixture with' the liquidto carbonate the ficulty by providing the receptacle with a rela-v tively wide mouth and a closure therefor with highly effective sealing means'between the closure and mouth, the construction and arrangement being such that the effectiveness of the sealing means is increased by pressure within the receptacle when the closure is applied and a charging" gas liberated withinthe receptacle.

Still another object of the invention is to pro- 75. vide a mounting for the capsule receiving chamvber, dispensing spout, valve, and controlling means for the valve, whereby such parts can be readily assembled as hereinafter pointed out and described.

The foregoing and other objects and advantages of the invention will become apparent and will be pointed out during the course of the following detailed description of the drawings,'in

which as Fig. 1 is a central vertical sectional view through a receptacle embodying the invention with a charging capsule positioned in its chamber; 1

Fig. 2 is a fragmentary detailed view on the line 2-2 of Fig. 1;

' Fig. 3 is a fragmentary view of a joint between the cover and container with parts broken away and partly in section showing a. modification of the sealing means between the container and cover;

Fig. i is a view similar to Fig. 1 showing a modification in the mounting of the capsule chamber, spigot, and valve operating means;

Fig. 5 is a top plan view of the mounting showninFig.4; and. Y Fig. 6 is a central vertical longitudinal sectional ,viewthrough a capsule constructed in accordance with the invention;

Referring to Fig. 1 of the drawings, the nuv meral 5 designates a container to receive liquids to be carbonated, and the numeral 6 designates the cap or closure which is secured to the container 5 by means of a bayonet joint or groups of interrupted interfitting, screw threads indicated no or chamber 32 in the transverse tubular portion generally at '7 and of known type. Any means suitable to quickly engage to hold the lid on the container against the pressure which will be created when charging gas is liberated within the container may be used, so that this feature forms no part of the invention.

The bottom of the container is preferably arched upwardly to form a dome 8, so that the container can be stood on the end 9 of the trough between the dome and the side walls 5. The purpose of this particular construction of the bottom is to take care of deformation which may result from pressures created within the receptacle without distorting the supporting surface 9 whereby the container will always have a level bottom surface. As is generally known, the pressures created withincarbonating receptacles are relatively high and hence the container and lid should be made of a material and of a thickness sufficient to withstand the pressures.

In order to tightly seal the receptacle between the lid or cover and the container 5, I provide the lid adjacent the flange 10, on which are formed the elements constituting part of the bayonet joint or interrupted screw threaded joint, with a tapered wall 11, and on the interior of the container 5 around its top edge or open mouth I mount a gasket indicated generally at 12 having a portion 13 contacting the interior of the walls of the container 5 and a flange 14 to rest on the top edge of the wall of the container. The gasket 12 also has above the flange 14 a tapering portion or flap 15 inclined approximately at the same angle of inclination as the wall 11 of the lid 6 and gradually diminishing in thickness toward its upper end. The gasket 12 is held in position and securely to the wall of the container 5 by a band or split ring 16 which is forced into the inner face of the portion 13 and against the shoulder 17 located slightly below the flange 14 and at the end of the tapering portion 15. It should be obvious that pressure within the receptacle will force the tapering portion 15 tightly against the tapering portion 11 of the lid 6 when the lid is applied to the container 5 as shown in Fig. 1, so that no fluid can escape between the lid 6 and container 5. Of course, the greater the pressure the more tightly the tapered portion 15 will be forced against the tapered portion 11 and hence the tighter the seal will be.

The lid has secured thereto on its interior, a frame or casting indicated generally'at 18, comprising an upright member 19 which extends through an opening in the top of the lid and having its upper end screw threaded to receive a nut 20. A bracket including a base 21 which rests against the top of the lid and through which the member 19 also extends is also secured to the top of the lid by the nut 20 which screws down against the base 21 of the bracket. The

upright member 19 is provided with a bore 22 through which extends a rod 23 connected at its upper end at 24 to an operating handle 25 pivotally connected at 26 to the upright portion 27 of the bracket. Rod 23 also extends through a relatively thick resilient block 28 above the nut 20, and'a metal'cap 29 which is mounted on top of block 28. The rod 23 can move downwardly through the cap 29, disc 28, and bore 22 when sufficient force is applied downwardly on the handle 25, to compress the resilient block 28.

The frame 18 also includes a cup-shaped depending portion 30 and in the top of which is formed a port 31 communicating with the bore 33 of the frame 18. A washer 34 is secured on the lower end of the rod 23 as by means of the cap nut 35 which has screw threaded engagement with the lower end of the rod 23, and it will be understood that the washer 34 is normally held against the port 31 and closing the same by resilient block 28 but when the block is compressed in the manner above stated by depression of the handle 25, the rod 23 will move the washer 34 away from the port 31. A tube, 36 has its upper end secured to a nipple 37 which is screw threaded into the cup-shaped portion 30 to hold the tube with its lower end preferably disposed in the trough above the'rim 9 between the dome 8 and side wall of the container 5. It will be noted that the nipple 37 and upper end of the tube 36 are in communication with the interior of the cup 30. Thus when the handle is depressed to compress the disc 28, the rod 23 moves the washer 34 away from the port 31 and communication is established between the interior of the receptacle, cup-shaped member 30 and the bore 32 of the tube 18, and the passage 38 in the spigot 39.

The spigot 39 may be of any construction but I have illustrated it as comprising a sleeve 40 mounted. on the outer end of the tube 33 with a screw 41 closing the outer end of the bore 32 which communicates with the passage 38 in the outlet 42 formed on the sleeve 40. The tube 33 also has an annular flange 43 adjacent the inside of the lid 6 and a packing ring 44 is inserted. between the flange 43 and the side of the lid 6, so that when the screw 41 is tightened up against the end of the sleeve 40, the packing will be compressed to seal the joint between the tube 33 and lid 6.

As has been mentioned, it is an object of the invention to provide means for inserting a capsule containing carbonating gas in compressed form from the exterior of the receptacle and to shield the capsule from contact with the liquid within the receptacle as well as to facilitate insertion and removal of this capsule. In order to accomplish these purposes I mount, preferably through a side wall of the lid 6, a screw threaded sleeve 45, the inner end of which has screw threaded engagement with the enlarged inner end 46 of the tube 33 of the frame 18. On opposite sides of the wall of the lid 6 and around the sleeve 45 are mounted washers 4'7 and 48 containing packing 49 within the channels provided therefor in the washers and around the opening through which the sleeve is mounted, to be compressed against the opposite surfaces of the wall of the lid 6 when the nuts 50 'are' tightened on the sleeve 45 against the washers 47 and 48. Referring to Fig. 2, it will be noted that when the wall of the lid is of circular or curved formation, as indicated at 51, the washer4'7 on the interior of the container will have a convex face and the washer 48 will have a concave face to abut the opposite surfaces of the lid.

The interior of the sleeve 45 when secured to the container as above described constitutes, in cooperation with the cap 52 which has screw threaded engagement with the sleeve 45, a closed chamber to receive a capsule 53 which is fllled with carbon dioxide either in solidified or liquefled form. A resilient bushing 54, which has its outer surface recessed to accommodate. the inner end of the enlarged portion 46 of member 33, is seated against the interior of the enlarged end 46 and has an arcuate seat 55 in its outer end to accommodate the curved shoulder'of the ing which time the user simply shakes the rethe capsule at a point calculated to lie without the end of the sleeve 45 when the capsule is in serted and in spaced relation theretd'the space between the bead and the end of the sleeve 45 preferably being substantially the same as the space between the inner end of the cap 52 and the outer nut 50 when the capsule is inserted and the cap is screwed down lightly against the end of the capsule 53 so that as the cap is tightened it'willforce the capsule inwardly so that the blade or pin will puncture the end of the teat 56 to permit escapement of the carbon dioxide through the passage 60 into the receptacle. As the cap' 52 is tightened the gasket 54 yields but it is impossible for the capsule to be moved inwardly any farther than permitted by the head 61 so that when the gas has been completely exhausted from the capsule and the cap 52 is removed, the capsule" 53 can be readily withdrawn from the interior of the sleeve 45'simply by taking hold of the bead 61 and pulling outwardly.

In use, the cover 6 is removed by turning relative to the container 5 in the manner generally followed. in separating parts joined by screw threads or bayonet joints; Inasmuch as the cap carries the frame 18 and all connected parts including the tube 36, the user simply fills the container 5 to the proper level with the liquid to becarbonated, then applies the cover 6 tothe container, removes the cap 52 from the sleeve 45, inserts a capsule 53 into the sleeve 45 and tightens the cap 52 as, far as possible or sufilciently to force the end of the teat 56 against the pin or blade 60 to accomplish puncturing of the end of the nipple whereupon the gas escapes from the capsule through the passage 60, durceptacle to carbonate the contents. As the capsule is forced toward the pin the shoulders are forced against the bushing 54 so that none of the gas can escape into the capsule chamber.

The gas passing through the passage 69 prevents liquid from entering into the chamber; and of course the walls of the chamber prevent the liquid from contacting the capsule. When the liquid is carbonated the handle 25 is then depressed and the port 31 is opened in the manner above described, so that the liquid which is now'under considerable pressure and carbonated will be forced by pressure in the top of the receptacle beneath the spout 39. I

, Th capsules will be proportioned v pacity f thereceptacle and will contain a. sufup throughv the tube 36 through the interior of the cup-shaped member 30, port 31, bore 32, andpassage 38 into the glass or other container held to the caficien't? charge to thoroughly carbonate a predetermined quantity of liquid so that when the carbonated contents of the receptacle have been exhausted or all used up it is simply necessary to remove the cover in-the manner already described if necessary to rinse out the receptacle and cover which is facilitated by the wide open mouths.

It will be readily seen that as the pressure increases within the receptacle,- the tapered portion 15 on the gasket 12 will be tightly forced against the wall 11 completely and tightly sealing the interior of the receptacle, and as the capsule is tightly forced against the gasket 54 and the washer 34 is tightly forced against the port 31 there is no possible source of escapement of fluid from the interior of the receptacle except by opening the port 31 for use.

' In Fig. 3, I have shown a modification wherein the lid 6' has a depending tapered skirt wardly for contact with the sk rt 65 of the l d.

The lid in this instance is shown as secured to the container 5' by means of bayonet slots '72. Under this form when the pressure is created in the receptacle the gas will enter'the'pocket between the walls and 71 of the gasket and force the wall 71 tightly against the skirt 65. It is preterable to have the wall '71- and the skirt 65 tapered to facilitate the sealing of the closure.

In Fig. 4 I have shown a modification wherein the capsule chamber is provided on the top of.

the cover and the valve and operating parts therefor are associated with the spigot. The structural details of the device shown in Fig. 4 are substantially the same asthose already described in connection with Fig. 1, and the diflerences are pointed out below.

The sleeve 45, Fig. 4, is mounted verticallyv through the top of the cover and is held securely in place by screw threaded washers 75 on opposite sides of the top of the cover and which compress packing 76 around the sleeve 45'. The cap 52', capsule-53 and bushing 54' are identical with those of Fig. l, but the casting 18' is diiferent from the casting or frame ,18, and has a screw threaded cu -like portion 77 to receive the sleeve 45 and bushing 54. The portion '77 is the same in function as the end 46 of frame 18 of Fig. l, but is located at the approximate center of the casting 18'. and the blade 58' is located in the end of portion '77 and a passage 60 is formed side of the cover to receive a screw '79 within whichis a packing 80. The opening which re ceives the end'of arm '78 is preferably of larger diameter than the end of the arm for a reason hereinafter pointed out. 0n the side of the position 33 opposite ar '78 the casting is enlarged to provide *a chamber 81. the lower end of which is closed by a nipple 3'7, similar to nipple 3'7, and carrying tube 36.

The wall of chamber-81 adjacent the wall of the cover is provided with a flange 82 to abut the interior of the cover and house packing 82' around the tubular stem 83 which extends from the chamber 81 through the side of the cover. The

adapted to be inserted through an opening in the stem 81 has a port 31 at its inner end and sup ports the spigot 39 on the exterior of the cover.

. Themechanism for openingandclosing port 31',

namely, valve, operating rod and handle therefor are the same as parts 34, 23 and 25 of Fig. 1, but mounted in a diilerent place and agetailed description need not be repeated.

To assemble the parts shown in Fig. 4 the casting 18 is inclined until the end of arm '78 can be passed through its receiving opening in the cover and the arm is passed through. said opening until the end of extension 83 can be moved up into the cover and inserted through its receiving opening with the packing 811 in place. The nut 79 and packing are applied, and the valve and operating parts, spigot, nipple 37' with tube 36 are then secured in place. The capsule chamber should be secured on portion 77 and to the cover before the-spigot 39 and nut 79 are tightened down.

The operation of the receptacle shown in Fig. 4 is the same as that of Fig. 1, it being apparent only that the capsule is inserted and the valve handle operated from difierent positions than in Fig. 1.

As hereinbefore mentioned, the invention also contemplates the provision of a particular construction of capsule especially adapted to be quickly and easily filled and sealed without the use of elaborate charging apparatus. This is accomplished by constructing the capsule, as shown in Fig. 6, of two parts A and B. The part A has the teat 56 at one end and the wall through which the piercing pin passes may be reduced in thickness as indicated at 90. The side walls of the part A are substantially straight and at their top are provided with a flange 91 providing a shoulder 92'against which the flange 93 of the part B rests when the part B is inserted into part A or into the flange 91. After the parts are thus placed together a gasket or packing 94 is placed on top of the flange 93 and by suitable apparatus, the flange 91 is crimped down against and around the packing 94 to the position shown in Fig. 6, thus firmly and tightly uniting the parts and sealing the carbon dioxide within the capsule.

The carbon dioxide or dry ice can be manufac tured in pellets of predetermined size so that a pellet can be readily dropped into the part A just prior to the assembling of the parts A and B in the manner above described.

It should be understood that the flange 91 of Fig. 6 corresponds to the flange 61 of Fig. 2 and the corresponding flange on the capsule 53' in Fig. 4, and that the size and shape of the capsule will be such as to assure ease of insertion.
